It can also be used for sealing cable and pipe entry ducts; temporary plugging of spare ducts and filling electrical glands and junction boxes.

Densyl Supersoft Petrolatum Mastic (Up to 75°C)

Filler for profiling irregular shapes to provide contours for subsequent tape wrapping were elevated temperatures are an issue. An integral component of Densyl tape systems for the preparation of surfaces prior to wrapping. Designed to withstand elevated temperatures. Densyl Supersoft Mastic is a filler for profiling around pipe joints, flanges, fittings, nuts, bolts and other irregular shapes to improve contours for subsequent tape wrapping.
